وَأَمَّا حَقُّ الصَّدَقَةِ فَأَنْ تَعْلَمَ أنَّها ذُخرُكَ عِنْدَ رَبكَ وَوَديعَتُكَ الَّتِي لا تَحْتَاجُ إلَى الإشْهَادِ عَليها، و كُنْتَ بمَا تَسْتَودِعُهُ سِرًّا أَوْثقَ مِنْكَ بمَا تَسْتَوْدِعُهُ عَلانِيَةً، و تعلم أنَّها تَدْفَعُ البلايا و الأسقام عنك في الدنيا، وتَدفَعُ عنك النار في الآخرة.
The right of charity (sadaqa) is that you know it is a storing away with your Lord and a deposit for which you will have no need for witnesses. If you deposit it in secret, you will be more confident of it than if you deposit it in public. [1] You should know that it repels afflictions and illnesses from you in this world and it will repel the Fire from you in the next world.
